DRILLING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 741,364, dated October13, 19031.

Application tied rune 20,1903.

To @Z whom, it may concern:

Be it known that I, CHARLES A. Orna citizen of the United States,residing at lVarren, in the county of Warren and State of Penn-Sylvania, have invented certain new and use- Y ful Improvements inDrilling Apparatus; and

I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to improvements in heads or barrels fordrilling-casings.

The object of the invention is to provide means whereby a hole may bedrilledin the earth irrespective of the surface upon which the device isoperated.

Another object of the invention is to provide means whereby adrill-casing may be retained in a iiXed position after the said casinghas been adjusted, so as to place the same in a perpendicular position.

The invention lconsists in the assembling of an adjustable drillcasing-with an outer cylindrical casing.

The invention further consists in providing` a drilI-casingwith a headcomprising an outer casing,a universal joint retained therein, and avertical and horizontal adjustable casing detachably secured in saidjoint.

The invention further consists in the combination of parts and novelconstruction, as is hereinafter more fully described, illustrated in theaccompanying drawings, and more particularly pointed out in the claimshereto appended.

In the drawings, Figure 1 is a sectional side elevation of theinvention, and Fig. 2 is a top plan view of the same.

Like numerals of reference designate corresponding parts throughout bothfigures of the drawings.

In the drawings reference-minieral 1 indicates an outer cylindrical orbell-shape casing of a head or barrel for a drilling tube or casing.rlhe said casing 1 is provided at its lower edge 2 with an annularbeveled portion. A concaved socket is formed in the top of the casing 1lAn aperture 4 is formed in the top of the said casing 1, through `whichis passed the adjustable inner or drill casing 5. The top of the saidcasing 1, in which the Serial No. 162,450. (No model.)

aperture 4 isformed, is constructed in the shape of a removable capsecured to the said casing l by suitable means, as at 7, which arepassed through apertures 8, secured in the coaching annular anges 9,formed upon the periphery of the said casing 1 and its cap 6. Secured toand adapted to pass through said cap 6 are several adjustablesquareheaded stud-bolts 10. lVithin the said easing 1 is secured aballor universal-j ointmember 11 by means of the cap 6 and the-concavedportion 3 of the casing l. Upon. this ball or spherical member 11 isformed guides or cut-out portions 12. The bolts or locking means 10 areadapted to engage these cutout portions 12 and retain said member 11 ina lock position. The said member 11 is provided with a central aperture,a part of which is threaded, as at 13. The inner casing is preferablyformed by assembling a removable cylindrical pipe 14 to the primaryinner casing- 15, and upon the said pipe or casing 14 is removablysecured an annular beveledged cap 16. At the outer endof the said casing15 is removably secured the drill-casing 17. Upon the periphery oftheinner casing 15 is formed screw-threads which are adapted to engage thecorresponding threads 13 upon the inner face of the aperture which isformed in the ball member 11. It will be apparent that the said innercasing by the construction of the ball or universal joint is adapted tobe removably secured within the casing 1 and alsoV permits of theadjustment of the same within the casing or head 1. A removable annularcap 18 ismountedupon the cap 6 and the inner casing 15, said memberlScompletely closing the aperture of said casing 1.

In operation the head or barrel is adapted to be placed upon adrill-casing, and the casing-1, coming in contact with the bottom of thechannel or stream, will sink into the sand or silt, and after the said.member has assumed a comparatively fixed position the inner casing canbe adjusted into a perpendicular position, irrespective of the positionof the outer casing 1. After this adjustment has been obtained the innercasin g may be retained in such position by means of the locking-screws10, secured to the cap G.

In the forming of holes for the reception of piles in hard or rockybottoms of streams or IOD channels it is necessary to employ a deviceconstructed on the principles .which are employed in my invention andwhich by experience I found overcome all objectionable features whichhave been experienced in the use of devices already patented.

It is to be understood that While I have described the preferred-form ofmy invention I reserve the right to make such modifications and changesin the dimensions of the machine as Will fairly fall Within' the scopeof the invention.

Having thus fully described my invention, What I claim as new, anddesire to secure by Letters Patent, isl I. A head for drill-casingscomprising an outer casing and an inner adjustable casing.

2. A head for drillcasings comprising an outer casing, a vertical andhorizontal adjustable inner casing.

3. In a device of the character described, the combination with abell-shaped outer casing, an adjustable casing removably retained Withinthe outer casing by means of a universal joint.

4. In a device of the class described, the combination, ofva cylindricalouter casing provided With a cap, a spherical member retained Withinsaid casing and a removable inner casing assembled with said casin g andits spherical member.

5. In combination, a bell-shaped member provided with a removableconcaved cap, a ball member secured Within said member and an innercasing mounted Within the ball member.

6. In combination,an outer casing provided with a socket, a ballretained therein, a central aperture formed Within said ball and meanscarried by said ball for retaining a casing Within the same.

'7. A head for drill-casings comprising` an outer casing and an innercasing adjustably mounted Within the outer casing and adapted to assumea position irrespective of that assumed by the said outer casing.

8. A head for a drill-casing comprising a bell-shaped member and aninner member and means for adjusting said inner member to a positionindependent of that assumed by said bell member. v

9. A head for drill-casings comprising an outer member provided with asocket, a ball member retained in said socket, andan inner casingremovably secured Within said ball member, means uponthe outer casingfor retaining the ball member in a fixed position.

10. In a device of the character described the combination With an outermember, a cap removably secured thereon, an apertured ball memberretained Within said casing, an inner cylinderical casing removablysecured Within said ball member, an annular collar removably mountedupon the outer casing and means for retaining the inner and outer casingin a fixed position relative to the said easings.

l1. In a device of the character described the combination of abell-shaped outer casing, an inner easing adjustably mounted therein,said outer casing provided with aremovable top, a socket formed Withinsaid outer casing, a sphere member retained Within said socket andlocking means carried by said top and engaging the sphere member foradjustably locking said inner casing` Within the outer casing.

12. A head for drill-casings comprising an outer casing formed of tWoparts, an inner casing provided with a beveled member and means for-adjusting the inner casing independent of the outer casing.

13. A head for drill-casings comprising an outer bell-shaped memberprovided With a socket, an apertured ball member retained Within saidsocket, an inner casing mounted Within the ball member, means upon theapertured ball member for locking said inner casing Within the outercasing, and an annular member removably secured upon said inner andouter casing for closing the aperture formed in the cap of said outercasino.

In testimony whereof I hereunto aiiiX my signature in presence of twoWitnesses.

CHARLES A. OTT.l
